“Businesses are placing a greater emphasis on skills training, investing in the workforces they have today and the one they will need tomorrow,” Upwork CEO Stephane Kasriel said. He added that since many "businesses might not be able to train up their workforce quickly enough," they are likely to depend on freelancers, who "are more likely than traditional employees to participate in skills-related education."

As technology has advanced in recent years, investments in big data solutions are also increasing. Hadoop, an open source software used to store, process and analyze big data applications, was the fastest-growing skill out of more than 5,000 skills freelancers provide on Upwork.com in Q4, the report said. It added that the business continues to invest in solutions that allow them to capitalise on the value of their data.

A majority of freelancers with a four-year college degree say skills training was useful rather than a college education. This gives freelancers to adapt to employee training as companies and firms have realised that reskilling of their workforce is quite important and critical for their business growth, the report added.

“Consumers now spend more than five hours a day on their smartphones, and apps account for more than 90 percent of internet time on those devices. Businesses are doubling down on their mobile efforts in order to meet consumers where they are, as evidenced by a spike in demand for app store optimization (#15) and app usability analysis (#16) in Q4,” Upwork said.
